In the drawing forming part of this specification I have shown a windowframe comprising side members a, a top member a and a bottom member aand I have also shown at Z; and b the top and bottom sashes providedwith the usual transparent panels 6 and in the practice of my inventionI secure to the opposite sides a of the window frame channeled casings6, having two separate channels 6 which correspond with the top andbottom sashes, and the inner walls of which are provided withlongitudinal slots or openings 6 having parallel flanges c forminggrooves 0 and the sashes I) and b are hinged to side bars havinglongitudinal tongues which lit in the grooves 0 and which are secured insaid grooves in any desired manner so that said bars are connected withand movable with the shoes 0.

The sashes b and I) are hinged to the bars f at 0 and in the form ofconstruction shown one of said sashes, the top sash, is hinged to thebar f at the left hand side of the frame, and the other or bottom sashis hinged to the bar at the right hand side of the frame. The sashes band b are also provided, in practice, with the usual counter-balancecords and counter-balance weights 9 one of said cords being shown inFig. 4:, and two of said cords and weights being indicated in dottedlines in Fig. 1.
